BNB Chain Testnet RPC Endpoints & Dedicated Nodes | OnFinality

Use OnFinality for BNB Chain Testnet RPC endpoints and dedicated nodes. OnFinality provides reliable infrastructure for developers testing smart contracts, building dApps, and preparing for mainnet deployment on BNB Chain Testnet.

What is BNB Chain Testnet?

BNB Chain Testnet (formerly Binance Smart Chain Testnet) is an EVM-compatible test network that mirrors the BNB Smart Chain mainnet. It uses the same Proof of Staked Authority (PoSA) consensus mechanism, offering fast block times (~3 seconds) and low transaction costs. Developers use BNB Chain Testnet to deploy and test smart contracts, integrate wallets, and validate backend services without risking real assets.

Why Use an RPC Endpoint for BNB Chain Testnet?

An RPC endpoint is the URL your application uses to communicate with the blockchain. Instead of running your own node, you can connect to a managed RPC endpoint to read blockchain data, submit transactions, and interact with smart contracts. OnFinality provides authenticated RPC endpoints for BNB Chain Testnet with HTTP and WebSocket support, archive and trace capabilities, and dedicated node options.

BNB Chain Overview

BNB Chain is a leading EVM-compatible blockchain ecosystem known for high throughput, low fees, and robust decentralization. It consists of BNB Beacon Chain (staking and governance) and BNB Smart Chain (smart contracts and dApps). With fast block times and Ethereum tooling compatibility, BNB Chain has become one of the most active smart contract platforms globally.
